Bupropion-Associated Skin Rash Management
Bupropion should be discontinued and urgent medical evaluation should be obtained when a skin rash suggests a hypersensitivity reaction or severe cutaneous adverse reaction (SCAR) [1], [2]. Discontinuation is recommended because bupropion rash can progress to life-threatening reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis [1], [2].
Immediate Actions for Rash During Bupropion Therapy
- Bupropion should be stopped immediately when a rash occurs with features concerning for allergy or systemic involvement. [1], [2]
- Emergency evaluation should be sought when any mucosal involvement, skin blistering or peeling, facial swelling, trouble breathing, or widespread rapidly progressive rash occurs. [1], [2]
- Non-emergent medical assessment should be obtained the same day when a new rash with pruritus, hives, or angioedema-like symptoms occurs. [1]
Severe Cutaneous Adverse Reaction Red Flags
Immediate discontinuation and urgent care are indicated for SCAR presentations, including Stevens-Johnson syndrome/toxic epidermal necrolysis spectrum reactions. [2]
Allergy and Anaphylactoid/Anaphylactic Reaction Features
Discontinuation and prompt consultation are recommended for allergic or anaphylactoid/anaphylactic reactions presenting with skin rash plus any of the following: pruritus, hives, chest pain, edema, or shortness of breath. [1]
Medication Rechallenge and Substitution
Rechallenge with bupropion after a suspected hypersensitivity or SCAR is not recommended. [1], [2]
Symptom Support Pending Evaluation
Supportive measures should be used while awaiting evaluation, including avoiding further doses of bupropion and obtaining guidance from an urgent care or emergency clinician. [1], [2]
Documentation and Risk Communication
The episode should be documented as a possible bupropion hypersensitivity reaction or SCAR, including onset timing and presence of mucosal symptoms, blistering/peeling, fever, or systemic symptoms, to support avoidance of future bupropion exposure. [1], [2]
Follow-Up After Rash Resolution
A new treatment plan should be arranged after discontinuation, with selection of an alternative for the original indication performed by the prescribing clinician after assessment of rash severity. [1]
